ROI of 3D Scanning for Custom Orthotics

An orthotics and prosthetics clinic needed to reduce the time and costs required for making custom orthotics, while making them more precise and comfortable. They turned to the Artec Eva 3D Scanner. Review the Return on Investment (ROI) for the clinic below:

Manual Measurement
Precision 3D Scanning with Artec Eva
Time 30 minutes for casting,
1 hour for measurement, 3 hours CAD design,
30 minutes’ milling and finishing.
3 minutes for 3D scanning,
20 minutes’ post-processing & CAD,
30 minutes’ milling and finishing.
Cost Approximate time: 5 hours Approximate time: 1 hour = 80 % time savings compared to traditional method.
Method Plaster casting together with tape measures and calipers,
with the final drawings being created in CAD software
and sent to the milling machine.
3D scanning patient’s feet from all sides with Artec Eva,
post-processing in Artec Studio, converting to CAD,
then sending to milling machine.
Level of Accuracy Slow and messy, as well as uncomfortable for patients.
High risk of inaccuracy.
Up to 0.1mm 3D accuracy



ROI per pair of orthoses Time Cost
Traditional + CAD 5 hours Full cost
3D scanning + CAD 1 hour = 80 % less time 69 % cheaper


Scan to CAD with Artec Eva, up to 0.1 mm 3D accuracy

It is 80% faster and 69% cheaper to create the custom precision orthoses compared to using traditional materials and manual measurement. The process using a 3D scanner is described below:

  1. SCAN: 3D scan all sides of a patient’s foot. Repeat for other foot.
  2. PROCESS: Post-process the 3D scans in Artec Studio and create precise 3D models.
  3. EXPORT: Send the 3D models to CAD and ready them for CNC milling.

Other advantages of using 3D scanning: SPEED, PRECISION & COMFORT

Casting and measuring casts of patients’ feet is messy, laborious, and time-consuming. Patients dislike it, and the final results can be less-than-ideal, which leads to product returns, bad reviews, etc. 3D scanning with an Artec Eva is fast and accurate, saving time and money, and the 3D models are easily archived for future use, unlike bulky plaster casts.
